What are the best practices for ensuring thread safety in programming?

To ensure thread safety, you can use techniques like mutexes, semaphores, and atomic operations. Would you like to know more about any specific technique?

Can you explain how mutexes work?

Mutexes, or mutual exclusions, are used to prevent multiple threads from accessing shared resources simultaneously. They lock the resource for one thread at a time.

What are some common pitfalls to avoid when using mutexes?

Common pitfalls include deadlocks, where two threads wait on each other indefinitely, and priority inversion, where a lower-priority thread holds a mutex needed by a higher-priority thread.

How can I detect and resolve deadlocks?

You can detect deadlocks by using timeout mechanisms or by implementing a deadlock detection algorithm. Resolving them often involves killing one of the threads or rolling back operations.
